I know what it is like to be physically present while my attention is somewhere else. Sometimes the distance is a phone. Sometimes it is work, pressure, or the mental list that never seems to close.
The answer is not pretending every night will become meaningful family time. Choose one small window that your child can actually feel.
The child-led window
Make the phone unavailable
Put it in another room or on its landing place. If you must remain reachable, allow the important contacts and keep everything else quiet.
Join their level
Sit on the floor, beside them, across the table, in the driveway, or in the passenger seat. The point is closeness that works for both people, not a particular pose.
Let them lead
Ask what they want to do or talk about. Resist improving the game, teaching a lesson, correcting the story, or steering toward your preferred activity.
End cleanly
Give a short warning before the time ends. Say what you enjoyed and, if you promise another time, make the promise specific enough to keep.
For an older child
Presence may look less like play and more like doing something shoulder to shoulder. Drive, cook, fish, walk, fix something, lift, or sit nearby without turning every silence into an interview. An invitation works better than an interrogation.
The short window is not a limit on how much time your child deserves. It is a beginning you can keep on a crowded day.
If you miss it
Do not make guilt the main event. Name what happened, put the phone down, and return. Children do not need a father who performs perfect presence. They need one who notices when he is gone and practices coming back.
